Pre-Algebra Lesson #21 Multiplying and Dividing Integers

In this lesson, we will learn how to multiply and divide integers. Basically, we will just figure out the sign of the product or quotient first and then work with the absolute values. We will spend some time developing the sign rules and then quickly go through some problems.
